Electric power simulation load device

Electric power simulation load device

Custom design and manufacturing available according to scale! Suitable for load testing of electric power meters.

This device is a load device used to test whether the electric meters installed in tenants of buildings and commercial facilities are correctly wired, by actually connecting a simulated load to consume power and checking if the meter's display is accurate. Resistors are used for the load, but the heated air generated is forcibly expelled and cooled, allowing for long-term use. The connection work with the power supply can be easily done with a dedicated cable. 【Features】 - Comes in a portable storage case - A switch allows for switching between three-phase power from the power panel and single-phase power from the lighting panel - The heated air generated is forcibly expelled and cooled, allowing for long-term use - Connection work with the power supply can be easily done with a dedicated cable *For more details, please refer to the PDF materials or feel free to contact us.

Three-phase load device "TKC-10 type"

Three-phase load device "TKC-10 type"

Built-in three-phase voltage output and three-phase current output! Testing can be conducted with just one unit of this device.

The "TKC-10 type" is a device used for conducting operational verification tests of AC measurement circuits and protection relay circuits in distribution boards and monitoring panels. It adopts the PT/CT secondary energization method, which allows for reliable testing during on-site commissioning and upgrades. It is compact, lightweight, and easy to handle. Additionally, the current phase can be easily switched (leading, in-phase, lagging) with just a switch operation. 【Features】 - Adopts the PT/CT secondary energization method, enabling reliable testing during on-site commissioning and upgrades. - Built-in three-phase voltage output (110V, 1A) and three-phase current output (5V, 5A), allowing verification tests to be conducted with a single device. - Current phase can be easily switched with just a switch operation. - Compact, lightweight, and easy to handle. *For more details, please refer to the PDF document or feel free to contact us.

Test resistance load device [Device for testing standalone operation prevention function]

Test resistance load device [Device for testing standalone operation prevention function]

Load capacity approximately 20kW! Supports three-phase unbalanced loads! Various settings can be changed according to test conditions, including three-phase and single-phase configurations.

The test resistance load device is intended for use in power conditioners for solar power generation systems, among others, to adjust the current balance during standalone operation prevention function tests or as a load for preventing reverse current. The maximum load capacity is 21.8 kW, which can accommodate up to five units in parallel operation for a typical household power conditioner (equivalent to 4 kW). 【Features】 ■ It is possible to switch between three-phase and single-phase according to the test voltage. ■ The load capacity increments are fine, with a minimum of 10 W (in single-phase), allowing for precise current balance adjustments. ■ In tests using three-phase power, the load for each phase can be set individually, enabling the creation of load imbalance conditions. ■ As a safety mechanism to prevent resistor burnout, two mechanisms are installed: the load will not engage unless the cooling fan is operational, and the power will be forcibly cut off if the resistor temperature exceeds a certain level. ■ Switches are available in two patterns: wired and wireless. ■ The wired switch comes with a 10 m cable, which can be extended up to 20 m with an extension cable. ■ The wireless switch is limited to the communication range of the wireless LAN, but distance extension is possible through the use of a relay.

Electronic Load Device for Eco Power Generation System 'F0374'

Electronic Load Device for Eco Power Generation System 'F0374'

Avoid battery overcharging and charging operation stop due to full charge! Automatically absorb only the surplus power!

The F0374 is an electronic load device for eco power generation systems that automatically absorbs only the surplus power to avoid battery overcharging or stopping the charging operation due to full charge in solar power, wind power, and hydro power systems for independent storage systems (12V, 24V, 48V battery systems). It is specialized for eco power generation aimed at absorbing only the surplus power generated by the system's generation capacity and maintaining the battery near full charge level. 【Features】 - Avoids stopping generation (charging) due to overcharging or full charge, and prevents zero display of generation data. - Allows for the evaluation of the generation system's performance by absorbing only the surplus power without excessive consumption. - With low self-consumption power, it can accommodate small-scale generation systems. - For large-scale generation systems, it can be operated in parallel with identical specifications. *For more details, please refer to the PDF materials or feel free to contact us.

Electric Power Storage Load Device "Denmaru-kun"

Electric Power Storage Load Device "Denmaru-kun"

"Denmaru-kun" reduces Japan's CO2 emissions by 2,400 tons!!

The power energy from load testing of self-generated power equipment has not been utilized until now. The power storage load device "Denmaru-kun" is equipped with a battery for EVs. It is now possible to store energy during load operation and use it as power for offices and EVs. According to a survey by the Japan Internal Combustion Engine Power Generation Association, the nationwide registration of fire-fighting and emergency generators is approximately 220,000 units. Assuming an average diesel generator of 100 kW, operating at 1/3 load for 30 minutes emits about 10 kg of CO2. If all emergency generators conduct load tests with "Denmaru-kun," it could lead to a reduction of CO2 emissions by approximately 2,400 tons, equivalent to the amount absorbed by 170,000 cedar trees in one year (according to our research). This CO2 emission reduction project is promoted by JESA. For more details, please contact us or refer to the catalog.
